For centuries, dreams have fascinated scientists and philosophers alike, yet no single theory fully ①explains why the sleeping brain generates such vivid and often bizarre experiences. One prominent idea suggests that dreaming helps the brain process emotional experiences, ②replays difficult events in a safe, low-stakes environment so that their emotional intensity gradually fades. Another theory proposes that dreams serve a more practical function, ③allowing the brain to rehearse responses to threats without any real danger. Still other researchers argue that dreaming is simply a byproduct of the brain organizing memories, with vivid imagery ④arising as the mind sorts through the day's information rather than serving any independent purpose of its own. Because these theories rest on indirect evidence, none has ⑤been conclusively proven.

After a strenuous workout, muscle fibers experience thousands of ①microscopic tears, and the body immediately begins a repair process that ultimately makes the muscle stronger than it was before. This repair depends heavily on amino acids, the building blocks that protein supplies, which is why sports scientists recommend consuming protein within a couple of hours after training. Waiting too long to eat can ②slow recovery, since a muscle's sensitivity to amino acids gradually declines once that window closes. Many athletes assume that eating an enormous quantity of protein in a single sitting will ③delay this process, but the body can only use a limited amount at once; the rest is simply burned for energy or stored as fat. For this reason, nutritionists generally advise spreading moderate portions of protein ④evenly across several meals throughout the day rather than saving it all for one large post-workout ⑤meal.

As technology continues to reshape nearly every profession, the idea of finishing education after graduation has become ①fashionable. Workers who once expected their initial training to last an entire career now find that skills can become obsolete within just a few years. Lifelong learning, therefore, has shifted from being an optional pursuit to a practical ②necessity for staying competitive in the job market. Companies that support this kind of continuous education often ③benefit as well, since employees bring fresh knowledge back into their daily tasks. Critics argue that constant learning can be ④exhausting and difficult to balance with personal responsibilities. Nevertheless, most career experts insist that those who resist ongoing education risk falling ⑤behind their peers.

For decades, athletes were taught to stretch a muscle and hold the position before any competition, believing that this practice alone would ①prevent injury. Recent research, however, has complicated that assumption considerably. Static stretching, in which a muscle is held at its longest length for an extended period, can actually ②reduce the muscle's ability to generate explosive force immediately afterward, which is troubling for sprinters or jumpers who need maximum power right away. Dynamic stretching, which involves controlled, repeated movement through a joint's full range of motion, appears to ③prepare muscles for activity without this temporary weakening effect. As a result, many coaches now recommend ④saving static stretching for after a workout, when it may help restore muscle length and reduce soreness, while reserving dynamic movements for the warm-up period before intense effort begins. The right technique, in other words, depends heavily on ⑤chance.

Even a modest level of dehydration, as little as two percent of body weight lost through sweat, can measurably reduce an athlete's endurance and cognitive sharpness during competition. As fluid levels drop, blood volume decreases, forcing the heart to work harder to deliver the same amount of oxygen to working muscles, which accelerates fatigue. Athletes competing in hot, humid conditions face a particularly difficult balance, because sweating heavily to stay cool simultaneously depletes the very fluids needed to sustain performance. Simply drinking large amounts of plain water is not always sufficient, however, since _______________. For this reason, sports scientists generally recommend a hydration strategy that replaces both fluid and electrolytes.

In the days leading up to an endurance event, many athletes deliberately increase their carbohydrate intake while reducing training volume, a practice known as carbohydrate loading. The strategy is designed to maximize the amount of glycogen, the storage form of carbohydrate, packed into muscle tissue before competition begins. Because glycogen serves as the primary fuel source during prolonged, intense exercise, _______________. Sports nutritionists caution, however, that the timing and composition of meals matter as much as the total quantity of carbohydrate consumed, since eating unfamiliar foods immediately before competition can cause digestive discomfort.

Limited-edition products are goods that are released in small quantities for a short period of time. Many companies use this strategy because ___________. When consumers believe that a product will disappear soon, they often feel pressured to buy it immediately rather than wait. For instance, a sneaker company that releases only a few thousand pairs of a special design can generate long lines outside stores overnight. This excitement is intensified by social media, where people proudly share photos of items that others could not obtain. However, this psychological pressure can lead to purchases that are driven by fear rather than genuine need. As a result, some shoppers later regret spending money on products they rarely use afterward.

Climate change deniers often seem to ignore evidence that contradicts their views, and psychologists have a specific explanation for this behavior. (A) For example, someone whose job depends on fossil fuels may search for reasons to doubt the data, even while insisting that they respect science. (B) This concept, called motivated reasoning, describes how people process information in ways that protect their existing beliefs and lifestyles rather than pursue objective truth. (C) Rather than being a simple failure of intelligence, this pattern reflects a well-documented psychological tendency studied for decades.

주어진 문장: This concern reflects a deeper fear about what makes art meaningful in the first place. Artificial intelligence has begun to play a surprising role in creative industries once thought to be uniquely human. ( ① ) Programs can now compose music, generate paintings, and even draft short stories within seconds. ( ② ) Some artists welcome this technology, using AI tools to explore new styles or overcome creative blocks that once took weeks to resolve. ( ③ ) Others, however, argue that AI-generated art lacks the emotional depth that comes from genuine human experience. ( ④ ) Despite this debate, most experts agree that AI is unlikely to fully replace artists anytime soon. ( ⑤ ) Instead, it functions best as a collaborative tool, helping creators experiment faster while leaving final artistic decisions to humans.

주어진 문장: Many of them said they had simply seen photos online and wanted to experience the space for themselves. Last spring, a small cosmetics brand opened a pop-up store in a busy shopping district for just two weeks. ( ① ) Rather than displaying products in the usual manner, the team designed the space to resemble a colorful garden, inviting visitors to explore and take photographs. ( ② ) Word spread quickly through social media as customers shared images of the unusual setting with their friends and followers. ( ③ ) Lines formed outside the store within days, even though the products themselves were already available online. ( ④ ) Curious about this success, a marketing researcher later interviewed several visitors, who explained that the temporary nature of the event made the experience feel special. ( ⑤ ) Many admitted they had never previously purchased from the brand but decided to buy something simply to remember the visit.
